Alternate Generic Amazon Fire TV Power Adapter

After reviewing the $24.99 stand alone Fire TV, I received several comments asking if there was a cheaper alternative to the official $19.99 Fire TV power adapter sold by Amazon. After doing some research, I ordered a few power adapters to test. The one I would recommend getting is this $7 power adapter from eBay. Be sure to select “6V 2.5A” from the Output Voltage dropdown menu, “Positive Pin Center” as the Pin Polarity, and “5.5mm x 2.5mm” as the Plug Size. It powered up the Fire TV and worked perfectly through all of my testing. It’s worth mentioning that the official Fire TV power adapter is rated at 6.25 volts, while the above power adapter is rated at 6 volts. I’m not an expert and can’t say if the lower voltage could damage your Fire TV, but my testing showed no difference between this generic power adapter and the official one. Amazon does not recommend using a power adapter other than the official one they manufacture.

Thanks! I appreciate you and everyone reading this just as much! I love being able to do this for everyone. The Fire TV community is one of the nicest ones I’ve ever been a part of, so it’s very satisfying to help where I can.

6V vs 6.25V won’t make much of a difference. My guess is they step it down to a lower voltage to power all the digital components (3.3V or lower). I would be surprised if you see issues since I’m sure they probably spec’d the input voltage to be around 5V-8V range.

Through the testing I’ve performed, the FireTV box will run perfectly fine on a 5v 3a, positive tip, 5.5mm x 2.5mm power supply. These power supplies are readily and cheaply available. My “portable” FireTV utilizes a custom power supply that splits off power for an external hard drive that requires 5v. It can be powered from the wall adapter or car adapter, both of which output 5v @ 3a. One note however, if you do as I’ve done, the power for the external hard drive cannot backfeed into the USB port. It will cause the FireTV to boot into a service mode of some sort.

Thanks for the info. The “service mode” you mention is called fastboot. If the Fire TV detects power coming into the USB port, it assumes you’ve connected the Fire TV to a PC, so therefore boots into fastboot mode (indicated by a frozen white Amazon logo on the screen). Fastboot mode is used to “flash” system images onto the device.

Try this at eBay: New AC Adapter for Amazon fire TV… This one is even better than the Original,I bought 8 of them ’cause I had a deal and bought 8 Amazon fire TV Boxes without the AC power adapter,so the above mentioned was the best option I had so far. I’ve been using it ever since with no problem… Just kill me if I’m wrong… I’m always right. LOL

Are there any similar generic adapters out there for the New Fire TV? I did see some low priced AC adapters on ebay for the Echo, which supposedly uses the same adapter as the new fire TV, but the specs say that it’s only 1 amp, whereas the Fire TV’s included adapter is 1.4 amp.
